电热干式保暖潜水服的设计研究

Design of an electrically-heated dry diving suit with thermal protection

目的设计一种应用自携式电源加热的保暖潜水服,解决潜水员水下低温保暖问题。方法采用防水、保暖和加热综合技术设计电热干式保暖潜水服,潜水服包括防水层、加热保暖层和水下电池组。结果无人实验和人体试验结果表明,潜水服具有水密、3.155克罗(CLO)保暖能力、电加热能力,可保障潜水员在(10±2)℃水温环境下维持体心温度35.8℃以上5 h。结论电热干式保暖潜水服可水下加热保暖,解决高压低水温环境下工作的低温问题,为潜水员提供水下所需热能,使潜水员在水下保持正常体温,有助于提高水下作业能力。

Objective To design an electrically-heated dry diving suit with a portable power supply for divers to keep warm in a low temperature underwater environment.Methods To synthesize the technological solutions of waterproofing,thermal insulation,and electrical heating,to design an electrically-heated dry diving suit with a waterproof layer,a heating and thermal insulation layer,and an underwater lithium battery pack.Results The results of both unmanned and manned testing showed that the electrically-heated dry diving suit with water tight,thermal protection with CLO value of 3.155,and electrically heating could,ensure that divers maintain their core body temperature above 35.8℃over 5 h in(10±2)℃underwater environments.Conclusion The electrically-heated dry diving suit can electrically generate heat and keep divers warm underwater,prevent hypothermia of divers and maintain their normal body temperature in a high pressure and cold environment,so as to improve their underwater operation capability.
